Tool Steel

420SS steel is a martensitic stainless steel known for its excellent hardness and corrosion resistance. After heat treatment, it can achieve high hardness while maintaining a certain degree of toughness, making it very suitable for manufacturing parts that require wear resistance and rust prevention, such as cutting tools, surgical instruments, and precision mechanical components.

As a benchmark for high carbon and high chromium cold work die steel, D2 steel's core highlight lies in the precise ratio of 12% chromium content and 1.5% carbon to form a large number of hard carbides. It maintains an ultra-high hardness of 60-62HRC while also having better wear resistance than ordinary tool steel (5-8 times that of ordinary steel). After appropriate heat treatment, D2 steel can significantly improve its anti cracking performance, especially suitable for high-strength wear scenarios such as precision punching dies and shear cutting tools. D2 steel, known as "semi stainless steel", also forms a passive film on its surface to delay corrosion, becoming a classic choice for balancing performance and cost in the industrial field.

1.2080 steel has high wear resistance and long service life, and is suitable for various cold stamping dies, cold shear blades, thread take-up plates and other complex and possibly deformed tool dies.

1.2083 steel is suitable for die casting of steel, die and pressure tools and light non-ferrous metal alloys that are easily affected by corrosive plastic and polymer tools and inserts.
